Question

Using the divisibility test, determine $726352$ is divisible by $4$, by $8$ or not?

Answer 1

Step $1:$ Explaining the divisibility test:

Divisibility test of $4$: A number is divisible by $4$, when the last two digits of the number is divisible by $4$

Divisibility test of $8$: A number is divisible by $8$, when the last three digits of the number is divisible by $8$

Step $2$: Finding whether $726352$ is divisible by $4$, by $8$ or not

The given number is $726352$

Last two digits in $726352$ is $52$

Clearly, $52$$÷4=$$13$

Thus, $52$ is divisible by $4$, therefore $726352$ is divisible by $4$

Last three digits in $726352$ is $352$

Clearly, $352$$÷8=$$44$

Thus, $352$ is divisible by $8$, therefore $726352$ is divisible by $8$

Hence, $726352$ is divisible by both $4$ and $8$
